help: 使用example项目创建的服务，启动后 apisix_log/error.log 一直warn

使用的是 example 目录，创建的docker 服务，error.log 一直 warn. 这个关系大吗，需要额外处理吗。

Please read your error logs carefully, it already tells you the fact. You should check why the ETCD cluster domain cannot be resolved.

@tokers 还能帮忙再看下吗，配置文件和服务都启动，上方截图。apisix 资料太少都是官网资料，kong的资料网上就多一些。

I already tell you the way.

This error log reminded me of this question: https://github.com/apache/apisix/issues/7715

In fact, if you have an environment that can be consistently reproduced, I would track it.

[cnn007]

ECS centos7.6

使用这个项目中的 example 中创建的服务 ，在两台ECS上，都是这种错误。你们可以docker创建试下。另外还需要提供什么资料。

Can you provide an online reproduction environment and send it to me via email? I don't have such an environment locally (I've started it many times via the example of the apisix-docker project without this problem)

要改为容器内的ip才行，域名解析有问题
